Initial Battery
•
The battery that comes loaded in your watch when you purchase it is used for
function and performance testing at the factory.
•
The test battery may go dead quicker than the normally rated battery life as noted
in the User's Guide. Note that you will be charged for replacement of this battery,
even if replacement is required within your watch's warranty period.
Low Battery Power
• Low battery power is indicated by large timekeeping error, by dim display contents,
or by a blank display.
• Operation while battery power is low can result in malfunction. Replace the battery
as soon as possible.
